PURPOSE:To improve operability, by automatically housing a disk carrier mechanism of a tray, etc., at the time of power supply OFF. CONSTITUTION:When turning ON a power switch 2 in a power source section, an ON signal is supplied to a control section 3, and the control section 3 supplies a normal rotation signal to a drive section 8. Then, a tray 5 is driven in the front direction, and when the tray 5 comes to the projection position, the control section 3 stops the supply of the normal rotation signal, and the tray 5 stops in the projection position. It waits in this state until a lead-in instruction signal or the power OFF signal is generated. If the OFF signal is generated during waiting, a control section 4 supplies a reverse rotation signal to the drive section. By this, a transistor Q1 in a drive section 8 is in the ON state, supplies the bias voltage +B to a motor 12, and the tray 5 is shifted to the housing position direction. When the tray 5 returns to the housing position, the power supply is turned OFF. By this, since there is no need to turn ON the power supply again to house the tray 5, the operability is improved. |
